How to get Video BIOS version from VGA controller. Is there any IOCTL
call ? Or, the mechanism of fetching BIOS version different among VGA
controllers.

Thanks in advance,

Arun

You can use v86 mode to call a VESA BIOS routine to fetch this information.
LRMI (the Linux Real-Mode Interface) contains a sample that shows how to do
this. Also, in X.Org or XFree86, the S3 Savage driver uses this technique.
